Abstract在实验室模拟炼油厂常减压塔顶冷凝水系统环境,用腐蚀失重法和电化学测试方法并结合扫描电镜(SEM)和X射线衍射(XRD)分析手段,研究90℃条件下低碳钢在含有不同浓度H2S的模拟溶液中的腐蚀电化学行为。结果表明,H2S强烈地促进碳钢的阴极过程,H2S浓度升高,阴极过程加剧,腐蚀速率加快;H2S存在时,电极表面发生严重的局部腐蚀而形成大量腐蚀坑,同时形成一层主要成分为四方硫铁矿的腐蚀产物,硫化物沉积层随H2S浓度升高而变得疏松、易于破裂和脱落。
Other AbstractThe electrochemical behavior of low carbon steel in acidic simulation solutions containing different concentrations of H2S at 90℃was investigated by mass loss method,electrochemical measurements and observations of scanning electron microscope(SEM) and X-ray radiation diffaction(XRD).The results showed that the cathodic depolarization was enhanced greatly and the corrosion rate of carbon steel increased remarkably with the increase of H2S concentration.The severe corrosion holes were observed on the carbon steel surface in the H2S-containing solutions.The corrosion products layer deposited on carbon steel were mainly composed of mackinawite,which became loose,easily cracked and sloughed off with increasing concentration of H2S.
